I’m in a bit of a quandary at the moment. On the one hand I have an un-reasoned, un-researched believe that Global Warming is real and is happening NOW! For example look at the way the polar ice sheets are melting and the way in which glaciers around the world are evaporating away.
On the other hand I went to England in Jan 2010 to visit with my mom who was having a pacemaker installed, and they were having the worst snow for years and years … of course that was until this Christmas that’s just passed, when it was even worse. Even here in Huntsville Alabama we got 8” just a week or so ago.
Of course the climate is a hugely complex beast. The arid and temperate bands tend to move around over time. Ten thousand years ago, for example, what we now know as the Sahara Desert was a lush, tropical paradise.
And then there are some folks who think we’re heading into another Ice Age. And others who say that the carbon dioxide we’re pumping into the atmosphere (that would promote global warming) is actually offsetting the onset of the ice age.
And there are so many things that can go wrong, or at least change in ways that will almost certainly be unfortunate for many of us, like the deep ocean currents stalling or changing direction, or a reversal of the Earth’s magnetic field, or the super volcano under Yellowstone Park letting go…
Still, you have to laugh (as they say), so I must admit that I really enjoyed an animation I just saw in which Global Warming is explained (or not as the case might be):
That may be the case for natural warming cycles which have occured in the past. But what scientists are primarily concerned about is man-made warming, since the data indicates it is occuring at a far faster rate than the geologically-recorded warming periods of the past.
Max. Loved the video! Here's a simple fact to debunk the global warming "scientists." I heard this from my meteorologist friend, but it was confirmed at a seminar at Stanford given by one of the "leading experts" in global warming and an adviser to Al Gore:
Historical measurements show that warming takes place BEFORE a rise in atmospheric CO2. The "scientist" claimed that it was indeed puzzling but nonetheless proved that CO2 CAUSED global warming.
I guess they now just have to work on new physics to show how an effect can precede a cause.
Max, per the polar ice sheets: If you look closely, you'll find that anytime someone mentions "decreasing ice volume", they are most often referring only to the Arctic (North Pole). Did you know that ANTarctic (South Pole) ice volume is actually increasing? I won't argue for or against Global Warming... I simply encourage people to do some reading on the "other side" of what they believe, then maybe the truth will be found somewhere in between. There are a lot of people making a living coming up with data on either side, so we would be wise to take their assertions with a bit of healthy skepticism.
Any speculation without data is just an educated guess. The data from all sources needs to be available for everybody to view. The interested parties, no matter their assigned standing in life, need to publish their scientific or other methods and conclusions. Once that starts rolling, progress can be made.
And how can we start? Simply, any one with known data should start publishing it on the internet. Various sites will emerge and various conclusions will be drawn. After time, agreement will be reached and can then be acted on.
Without a traceable map of various people's sources and efforts, no consensus will be reached by enough people to make a difference.
Good Point -- I hadn't thought about that. Also I read somewhere that the warming effects in some layers of the atmosphere were being offset by some other effects in other layers of the atmosphere, but that these other effects wouldn't last...

Increasing snowfall is not an indicator of colder weather as much as it's an indicator of increased moisture content in the atmosphere. This is something predicted consistently since over 15 years ago, that global warming would lead to increased moisture content and more water in storms in all seasons.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for todays commercial processor giants such as Intel, ARM and Imagination Technologies.
